Software Engineer with 3+ years building production fintech, transport, and AI applications — now transitioning into Application Security Engineering.

Building Software
The Secure Way

I'm a detail-driven Software Developer with 3+ years of experience across Angular, React Native, React.js, Next.js, Node.js, Express.js, Firebase, MongoDB, and PostgreSQL. I build elegant, scalable interfaces for web and mobile — and increasingly, I integrate AI and LLM-powered features (chat interfaces, adaptive learning, automated workflows) using prompt engineering to make them genuinely useful. Underneath all of it: the same instinct for authentication, payment security, and clean data handling that's now pulling me toward Application Security Engineering.

Secure By
Design.

Alongside my BTech in Computer Science, I've independently studied the CIA Triad, threat vectors, the OWASP Top 10, and ethical hacking fundamentals — getting hands-on with Burp Suite, Nmap, and Wireshark. Now formalizing that shift into a dedicated Application Security Engineering role.
